Pesticides are substances meant to kill or control pests.
The Vyan once used a chemical called Dargol as a pesticide. It had a significant impact on the environment and fertility rate though, so it was banned. (SG1: "Past and Present")
The Tau'ri had a problem similar to Dargol with a chemical called DDT. It built up in the food chain until entire species were threatened. (SG1: "Past and Present")
Stargate Command attempted to use a pesticide during the Skirmish with the Virus Orb but it didn't slow the A't'trr down. (SG1: "Message in a Bottle")
The Ethloninans developed a potent pesticide to combat a plague of Mutated locusts brought to their world by Klorem. They were fully aware that this pesticide would cause irreparable damage their world's ecosystem. (RPG: "Ecology")
